Please help me answer this question on migration form

Give details of how you financially support yourself, including how long you have received this support for and how much you receive on a monthly basis?

Background: dh has been employed as an international civil servant for the past 7 years during which time I have (happily) followed him across 3 continents home-educating our four children. With the exception of a few doula clients, I have not been gainfully employed.

Dh has been offered a sponsored academic position in Austalia and this is the last question I need to answer on my visa application form. It has kept me awake most of the night feeling inadequate.

No guidance, but bumping. I'm facing a similar situation filling in an advanced clearance form for the ministry of justice to get clearance for prison visiting- I've not been on benefits or employed for much of the last 10 years.
